Description

A kind of elm implantation methods

Technical field

The invention belongs to forestry planting technology field, be related to it is a kind of using green manure " rattail fescue grass " improve autumn plantation seedling at Motility rate, the elm plantation for saving weeding cost.

Background technique

Elm also known as Japanese elm, American elm etc. are known as the title of " elm pimple ", belong to Ulmaceae, Elm deciduous tree.Its height can Up to 25 meters.Its wood is tough and tensile, and texture is sensible clear, and hardness and moderate strength, planing surface is smooth, and chord plane decorative pattern is beautiful, is applied to height Grade furniture, cabinet, carved lacquerware handicraft article etc..Elm is to use material plant, medicinal plant, green plants, and economic value is very huge.

Elm light, it is drought-enduring, it resists cold, it is barren-resistant, soil is not selected, adaptability is very strong；Well developed root system, wind resistance power, soil conservation power By force；Rudiment power is strong, resistance to trimming；Growth is fast, and the service life is long；Resistance to dry and cold weather and moderate are saline and alkaline, but (are resistant to rainy season water intolerant to water-wet Flood)；Resistance tocrocking, blade face regulation of absorbing dust capability are strong.Be distributed in Northeast China, North China, each provinces and regions in northwest and southwest, Korea, the former Soviet Union, Mongolia is also distributed, and is born in 1000~2500 meters of height above sea level or less of hillside, mountain valley, valley, hills and sand hill etc., in soil depth Alluvial soil and loess plateau well-grown thick, fertile, draining is good.Can make northwest desert, North China and Soil Development in Huaibei Plain, hills and Northeast deserted mountain, the afforestation of sandy ground and beach saline land or " by the of four " green tree species.

Summary of the invention

The invention aims to solve above-mentioned technical problem, a kind of elm implantation methods are provided, are planted using woodland green Fertilizer " rattail fescue grass ", inhibits weeds for a long time, improves soil, improve winter ground temperature, and then improves elm autumn plantation kind shoot survival percent, Save weeding cost.

To achieve the goals above, technical scheme is as follows:

A kind of elm implantation methods, comprising the following steps:

Step 1 determines implantation time, and elm is planted in the first tenday period of a month in late October to November, and rattail fescue grass is planted in the first tenday period of a month in October, Between the two every two weeks to one month, preferably planted before rain；

Step 2, site preparation are removed intramassif weeds clean；Using mechanical rotary tillage, 10~15cm of depth；Equably by base manure It dispenses in soil surface, ploughs under fertilizer in soil in conjunction with rotary tillage；Planting pit, cave diameter 0.4 are dug by elm seeding row spacing 2m × 1.5m ~0.6m, deep 0.4~0.6m；Elm row both sides are from the ditch that begins to rehearse at 30~50cm of tree；

Further, base manure is mixed by organic fertilizer, compound fertilizer, and important portion rate is organic fertilizer: compound fertilizer=20:1, 300Kg/ mus；The compound fertilizer be one of balanced type compound fertilizer (15~15~15), calcium magnesium phosphate or more than one；

Step 3, elm select seedling and seedling process, select not damaged well developed root system, no disease and pests harm, healthy and strong annual elm real Raw seedling；Before transplanting, seedling root system is impregnated into 0.5~1h in protective agent；

Further, protective agent is compounded by 25ppm ABT3 root-inducing powder medical fluid, 1g/L phoxim medical fluid；

Step 4, the sowing of rattail fescue grass, in the ranks kind is broadcasted sowing by 1.5~2kg/ mus of application rate as rattail fescue grass seeds growing area in plot to elm Son after planting gently draws earthing with creeper, pours a water；

The subsoil for digging cave and base manure are first mixed, by the cave 2Kg/, insert cave bottom, then cover above by step 5, elm field planting Then seedling is placed on planting pit center as separation layer by the thick soil of lid 2~5, trunk righting backfills surface soil, then mentions seedling, steps on It is real, it flushes with ground, is sprinkled profoundly water after field planting；

Further, green manure seed is put into 3~6h of immersion, more a step in 30~50 DEG C of gibberellin dilutions of constant temperature prior to seeding , the gibberellin dilution is 6% gibberellin water aqua, 800~1000 times of liquid；

Further, rattail fescue grass seed is mixed with sawdust, fine sand mixed prior to seeding, and mixed proportion is seed: sawdust: fine sand=1:10: 3, it mixes mixed rear moisture content and was sowed at 40~50%, second days；

Step 6, fertilizing management, in the middle ten days and the last ten days in March, top dressing is primary, elm balanced type compound fertilizer (15~15~15) 100g/ Strain, 6~8Kg/ mus of rattail fescue grass；The middle ten days and the last ten days in may, then top dressing are primary, and 100g/ plants of elm urea, 6~8Kg/ mus of rattail fescue grass.Elm Tree is applied fertilizer using buried Casing ways, and rattail fescue grass directly broadcasts sowing fertilising, is watered after fertilising.Dose is fitted as elm grows up Work as increase, and rattail fescue grass dose is finely adjusted according to growing way.

Mainly have the advantage that including the following:

1. weed growth can be inhibited for a long time, do not have to weeding within 3~5 years using green manure " rattail fescue grass " in the present invention；Its root system it is deep and Intensively, can prevent soil loss in growth period, root system is withered rot after can supplement soil with organic matter, keep soil permeability With aeration；Its root system is very thin, has the effect instead of manually deep ploughing after rotting, is able to maintain soil stability, is retained, moisturizing, It is waterlogging-resistant；Summer resists sunlight being directly exposed to the sun to exposed soil, reduces the generation of rainy season damage caused by waterlogging, and plays heat preservation in winter Effect.Rattail fescue grass can effectively improve soil, keep soil stability, and then improve Forest soil miniclimate；

2. rattail fescue grass seed first carries out vernalization processing prior to seeding, is conducive to improve germination percentage, saves seed dosage；

3. rattail fescue grass seed is mixed with sawdust, fine sand mixed prior to seeding, be conducive to sow more uniform.
